On April 30, 1598, during a ceremony on the banks of the Rio Grande, Oñate performed
La Toma. He declared that all lands drained by the river were now possessions of
King Philip II of Spain. This act was not merely ceremonial; it served as a legal justification for his subsequent military actions against local
Pueblo tribes. Oñate's proclamation included a solemn oath that he would govern these territories with "peace, friendship, and Christianity," emphasizing his intention to convert indigenous peoples to Catholicism while asserting Spanish dominion over their lands. The declaration was framed within the context of Spanish imperial law, specifically referencing the
requerimiento, which mandated that indigenous peoples be informed of Spain's claims to their lands and offered a chance to accept Spanish rule peacefully before any military action could be taken. == Consequences and historical significance ==
